China’s composite-resin supply chain covers unsaturated polyester, vinyl ester, epoxy, polyurethane and application-specific gelcoats for pultrusion, winding, infusion, hand lay-up, RTM, SMC/BMC and coating. Grade names alone are not portable between producers. A sourcing specification should define process viscosity window, gel time or cure schedule, mechanical target, chemical exposure, flame requirement, colour and storage conditions.
For export procurement, consistency and documentation matter as much as the first laboratory result. Buyers should request a current technical datasheet, safety data sheet, certificate of analysis format, shelf life, storage temperature, inhibitor or promoter condition, dangerous-goods classification and packaging. Gelcoat RFQs should also define application method, target wet-film thickness, UV and water exposure, colour tolerance, gloss and whether the system is mould-side or post-applied.
GetFRP compares public manufacturer and formulation-capable supplier profiles by chemistry, process, end use, capacity tier, export packaging and available evidence. Buyers can visit the company profile or official website before requesting a quote. Before a production order, the recommended route is a controlled lab sample followed by a plant trial using the buyer’s reinforcement, catalyst package, ambient condition and equipment, with acceptance criteria recorded before scale-up.

Buyer FAQ
How do I choose between isophthalic polyester and vinyl ester?
Vinyl ester is generally selected for stronger corrosion resistance and toughness, while isophthalic polyester can be economical for moderate industrial exposure. The decision needs the actual chemical, concentration, temperature, stress and service life. Confirm it with resin guidance and a representative laminate trial.
Can I compare resin prices by kilogram?
Only after normalising solids, additives, packaging, Incoterm, dangerous-goods cost, shelf life and process yield. A lower resin price can be offset by slower cure, higher scrap, extra promoters or a poorer surface. Compare cost per accepted part or laminate output.
What should be included in a gelcoat colour approval?
Use a defined substrate, application method, wet-film thickness and cure. Record colour standard, gloss, surface, weathering requirement and measurement geometry. Keep a signed master panel and define the allowable colour difference for production batches.
Why is a plant trial necessary after a lab sample passes?
Resin behaviour changes with reinforcement, part thickness, catalyst system, temperature, humidity, mixing and equipment. A plant trial validates flow, wet-out, cure, exotherm, surface and cycle time under the actual process before commercial volume is committed.
